putchar is a dinosaur macro.  the diagnostics make sense after expansion.

even more amusing, try to suppress them by including an ugly
lint-style cast to void, and you'll get a further such diagnostic
(and serve you right for adding clutter)!

more helpfully, if you're writing a new program for Plan 9,
use bio(2) instead

i'm only getting half of this conversation on the list.
does this have anything to do with the putchar email
that quoted an email that wasn't on the list?
